IMPROVEMENT IN DOOR-CHECKS.

Specification forming part of Let-ters Patent No. 221,873, dated November 18, 1879; application filed September 6, 1879.

To all 'whom it may concern:

Be it known that I,r GEO. H. SMITH, of Webstelgin the county of Taylor and State of WestVirginia, have invented certain new and useful Improvements in Door-Checks; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and

to theletters of reference marked thereon whichl to vwhich my invention appertains to make and use the same, I will now proceed to describe its construct-ion and arrangement.

A represents a short steel bar, one end of which 1s secured to the iloor at the point at which it is desired to hold the door, as shown. The opposite end of this bar is made thinner, and forms a spring, the upper surface of which is cut away to form a step, a, and is held up against the under surface of the door by means of an adjustable screw-bearing, b, by which it may be raised or lowered to suit the different doors. The extreme upper end of this bar A, beyond the step a,`is also provided with a series of holes, c c. v

B is another metal bar, one end of which is secured to the floor in such position that it will be at right angles, or nearly so, to the bar A. The opposite end of the bar B rests upon the upper end of the spring-bar A, and

is provided on its' underside with a pin or projection, d, which passes through one of the holes c, (according to the thickness of the-door,) and retains the end of the bar B in position.

The bar A having been secured at right angles to the position of the door, when open, the door is swung back, and sliding over the bar A the outer end of this bar is depressed, and the door passing over the step u., the bar springs up into its positionagain, holding the door between the step or shoulder a and the end of the bar B.

When'it is desired to shut the door, the foot is pressed upon the barB, and the door, being thus released, can be closed.

It' desired, the surface of the door sliding upon the sprin g mayA be bound or covered with sheet metal to prevent wear.`

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. The combina-tion of the spring-bar A, having the screw-bearin g b, with the stop-bar B, substantially as and for the purpose set forth.

2. The within-described device for holding doors open, consisting of tlie spring-bar A, provided with an adjusting-fulcrum, b, step a, and holes e c, combined with the stop-bar B, provided with spur d, all constructed and arranged to operate substantially as and for the purpose described. g

In testimony that I claim the foregoing as my own I atx my signature in presence of two witnesses.

GEORGE HENRISON SMITH.
